Seven years may be a long time for ordinary mortals, but for cultivators, seven years is only equivalent to a blink of an eye. When Kong Yu returned to the Yin Yang Temple, the situation in the Yin Yang Temple was still the same as when he left, Lao Tzu and the others were still cultivating, and the Great Heavenly Venerable Yang Feng was also consolidating his realm and preparing to leave the Continent of the Gods, so for a while, Kong Yu didn't know what he should do.

Hua Yue'er and Tang Mei'er came to the Yin-Yang Temple for the first time, and they were also extremely shocked when they saw the divine tree standing in the Yin-Yang Temple, but after experiencing so many things, the two of them have also matured a lot, and they are no longer the little girls they used to be, although they were very shocked in their hearts, they didn't shout, after all, there were still so many people cultivating in retreat under the Divine Tree, and it was not good to disturb them.

Kong Yu sighed, it seems that he really didn't work hard enough, if it weren't for his master who had arranged everything for himself, so that he could get to the current realm step by step, with Kong Yu's heart, he really wouldn't have cultivated so hard, looking at the cultivators, Kong Yu thought about what he was going to do, for the time being, he still didn't want to cultivate, he just wanted to relax, after all, the days of cultivation in the future were still long, and he didn't want to leave the world of the Continent of Gods in a hurry like Yang Feng, the Great Heavenly Venerable, so it didn't matter whether he cultivated or not, as long as he had the ability to protect this Continent of the Gods, it was enough。

In the past seven years, Kong Yu has summoned his parents, grandfather and various disciples to the world of the Continent of the Gods, condensed the World Tree for each of them, and then let them experience in the Five Great Divine Domains, all the things he can think of have been done, and now he really has nothing to do.

Kong Yu looked up at the divine tree that stood in the entire Yin Yang Temple, and suddenly thought of one thing, that is, this divine tree can penetrate other cosmic worlds and absorb Xuanhuang Mother Qi from other cosmic worlds, and Xuanhuang Mother Qi plus the soul fire he ignited can make his spiritual treasure produce a tool spirit and transform into a real artifact.

Just do it when you think of it, this is the principle that Kong Yu has always pursued, since he wants to refine his own spiritual treasure again, Kong Yu naturally will not delay time, came to the bottom of the sacred tree, sat down, and summoned his spiritual treasure. Kong Yu now has a lot of spiritual treasures, the Killing God Spear, the Six Reincarnation Heavenly Disk, the Eastern Emperor Bell, the Nine Dings, and the Twelve Heavenly Demon Divine Flags, these five spiritual treasures are also famous in the Pangu Zhoutian world, and as Kong Yu has been refining with the power of the world for so many years, it has also evolved a lot.

Looking at the five spiritual treasures in front of him, Kong Yu thought about it for a while, and decided to refine the Heavenly Demon Divine Banner first, after all, this was the first spiritual treasure that Kong Yu had gotten, and it had been with him for the longest time, and it was also for Kong Yu to resist a lot of disasters, and now that he had the opportunity to promote them to artifacts, he naturally had to choose this Heavenly Demon Divine Banner first. And after choosing, Kong Yu immediately started refining.

I saw Kong Yu's mind move, and a ball of flickering white, cyan, black, red, and yellow flames appeared on the top of Kong Yu's head, suspended above Kong Yu's head. This is naturally Kong Yu's Five Elements Soul Fire, at this time, Kong Yu's Five Elements Soul Fire has become more condensed, the light is flickering, people can't look directly, exuding an extremely powerful aura, and when the Five Elements Soul Fire appeared, a stream of Xuanhuang Qi was emanating from the sacred tree, throwing towards Kong Yu's Five Elements Soul Fire, blending into it, and fusing with the Five Elements Soul Fire.

Seeing this situation, Kong Yu pointed to the Dutian Demon Divine Banner placed in front of him, and suddenly the Dutian Demon Divine Banner turned into a streamer and flew into the Five Elements Soul Fire on the top of Kong Yu's head, and then Kong Yu began to refine it according to the refining technique passed on to him by Yang Feng of the Great Heavenly Venerable, because it was refined with soul fire, Kong Yu's soul directly penetrated into the Dutian Demon Divine Flag, and every minute of the Dutian Demon Divine Banner was clearly checked.

Kong Yu checked the structure of the Dutian Demon Divine Flag, and after thoroughly understanding it, he began to directly use the soul power to make one seal after another according to the refining technique of the Great Heavenly Venerable Yang Feng, and entered the Dutian Demon Divine Flag, and at the same time continuously poured Xuanhuang maternal qi into the Dutian Demon Divine Flag, making the Dutian Demon Divine Banner evolve little by little, and constantly approached the ranks of the artifact.

If you want to refine a spiritual treasure into an artifact, it is not an overnight thing to produce a spirit of the instrument, Kong Yu is also very patient, not in a hurry at all, and constantly absorbs Xuanhuang maternal qi from the sacred tree and pours it into the Dutian Demon Divine Flag, and in this way, half a year has passed, and finally the Dutian Demon Divine Banner has undergone earth-shaking changes. Although the original Dutian Demon Divine Banner was very powerful, it was filled with evil energy, and now the re-refined Dutian Demon Divine Banner not only increased its power a lot, but the evil qi on it also disappeared, and was replaced by a stream of Xuanhuang Mother Qi.

Seeing such a situation, Kong Yu knew that he had already succeeded halfway, and he was naturally very happy in his heart, but now it was the most critical time, which was to leave a trace of Kong Yu's soul in the Dutian Demon Divine Banner and derive the instrument spirit of the Dutian Demon Divine Flag, which was the most critical thing and the most difficult thing.

Kong Yu naturally didn't dare to take it lightly, and carefully separated a trace of his Five Elements Soul Flag, and slowly poured it into the Dutian Demon Flag, and after this trace of the Five Elements Soul Fire entered the Dutian Demon Flag, the entire Dutian Demon Banner trembled violently, and the breath coming from it became stronger and stronger, and a roar faintly came out of it, as if a world-famous beast was waking up.

Seeing such a situation, Kong Yu knew that this was the Dutian Demon Divine Banner that was deriving a weapon spirit, so he was naturally very nervous, and as time passed, one after another phantoms gradually condensed on the twelve Heavenly Demon Divine Flags, and the appearance of these phantoms was exactly the same as the Twelve Demon Gods, which made Kong Yu's eyes widen, and he couldn't believe that what was happening in front of him was true.
